Trump "walking away" from the Constitution among reasons Pence won't endorse

What he's saying: "I said it during my presidential campaign — the president and I have profound differences. Many people think it's just over January 6th and, frankly, the fact that the president continues to insist that I had the right to overturn the election that day is a fundamental difference," Pence said Sunday on CBS' "Face the Nation."

• "But, I want to be clear that I've forgiven the president in my heart for what happened that day," Pence said.
• Pence listed Trump's "walking away" from "a commitment to fiscal responsibility, a commitment to the sanctity of life [and] a commitment to American leadership in the world" as other reasons he wouldn't endorse the former president.

Catch up quick: Pence said his decision not to back Trump "should come as no surprise," per an interview Friday on FOX News Channel's "The Story with Martha MacCallum."

• Pence said he preferred to keep his vote private, though he specified that he would "never vote for Joe Biden," who recently became the presumptive Democratic nominee.

Zoom out: Pence, who served under Trump as vice president for four years, has been vocal in his criticism of the former president following the Jan. 6 Capitol riot.

• He ended his own presidential bid last October amid a crowded Republican primary.
